Description

Integrated alarm purse net and installation method thereof

Technical Field

The invention relates to the technical field of electronic fences, in particular to an integrated alarm purse seine and an installation method thereof.

Background

The electronic fence is a boundary protection system realized by utilizing an electronic technology, can be used for monitoring and controlling the access of a specific area, is applied to various scenes, comprises home security protection, site protection, military facility protection and the like, and is the most advanced perimeter anti-theft alarm system at present. The electronic fence is composed of an electronic fence host and a front-end detection fence, wherein the front-end detection fence comprises a tangible perimeter formed by components such as a rod, a metal wire and the like, and the electronic fence host can generate alarm signals when the front-end detection fence is in a network touching, short-circuit and open-circuit state and sends the intrusion signals to a safety alarm center.

An electronic fence host is typically comprised of a sensor, a controller, and an alarm system. The sensor is deployed around the fence or in an area to be protected, and can be an infrared sensor, a microwave sensor, an ultrasonic sensor, a piezoelectric sensor, an acceleration sensor and the like, and is used for detecting whether a person or an object enters or leaves the fence area. The controller is responsible for receiving the sensor information and responding accordingly, such as triggering an alarm, sending a notification, etc. The alarm system is used for timely warning security personnel or system managers.

Problems with current electronic fences include: false positives and false negatives. The sensor is very sensitive to external vibrations or shocks and may therefore be affected by external disturbances, such as wind blows, vehicle passes, etc., resulting in false alarms. On the other hand, if the sensor is improperly set or damaged, a true intrusion event may not be accurately detected, resulting in a false negative. External interference: external environmental factors such as strong wind, earthquake and the like can also influence the vibration electronic fence, so that the problem of false alarm or missing alarm is caused. These interfering signals may be similar to the intrusion signals, increasing the difficulty of identifying the fencing system. False perception: the electronic fence can also generate signals when some external vibration such as animals, plants or other objects collide with the fence, and can be mistaken for an intrusion behavior, so that false perception is caused.

In addition, the electronic fence is used for boundary protection, and in some specific use scenarios, such as areas with complex terrains, how to realize quick installation and ensure that the detection of the sensor is not affected after the installation, no good solution exists in the prior art at present.
